voluminous quaternary extrusive rocks, associated with widespread volcanic activities, occur in the northwestern iran and across the turkish-iranian plateau. field and petrographic studies reveal that these volcanic rocks, consisting of basalt to trachyandesite, occur as lava flows, columnar basalts, and cinder cones in three distinct areas of northern (bazergan-maku-burlan), middle (chalderan)...

While hotspot tracks beneath thin oceanic lithosphere are visible as volcanic island chains, the plume-lithosphere interaction for thick continental or cratonic often remains hidden due to lack of volcanism. To identify plume with missing volcanism, we characterize amplitude and timing surface heat flux anomalies following a using mantle convection models. Our numerical results confirm an analy...

Abstract The Aristarchus plateau hosts a diversity of volcanic features, including the largest pyroclastic deposit on Moon, sinuous rille and intrusive extrusive examples evolved, Th-rich silicic lithologies. We provide an overview previous remote-sensing measurements new analyses Diviner Lunar Radiometer thermal IR data, Prospector Gamma Ray Spectrometer Th Chang’e-5 Microwave hyperspectral mu...

Volcano Young Sheveluch is one of the most active volcanoes in Kamchatka. Since August 1980 to present time, an extrusive dome has been growing crater volcano. Plastic lavas form large ribbons were noted on already 1980–1981, first lava flow was observed after a paroxysmal eruption May 9, 2004. The next block started extrude end April – beginning 2020. By June, 11th, it rose above 50–80 m, and ...

Formed on top of the Gulf Cadiz, Al Idrissi mud volcano is shallowest and largest in El Arraiche field northwestern Moroccan margin. The development morphology volcanoes from group have been studied at a large scale. However, time interval related to their formation period still needs be better understood. In this regard, we interpreted analyzed seismic facies 2D reflection data GEOMARGEN-1 cam...

Abstract The increase in number and intensity of earthquakes during a pre-eruptive crisis is the main basis seismic volcano monitoring. However, strong understanding how these signals relate to magmatic processes magma plumbing systems prior volcanic eruptions crucial for efforts. Here we compare characteristics seismo-volcanic 2010–2013 explosive-extrusive eruption Kizimen volcano, Kamchatka w...

Seafloor spreading magnetic anomalies of oceanic plates progressively decay and disappear when approaching entering subduction. Previous studies focused on the Japan Trench showed that before subduction, flexure lithosphere opens normal faults rejuvenates hydrothermal circulation which results in alteration minerals. After thermal demagnetization affects minerals crust increasing temperature su...
